Despite the previous answer, after receiving additional information from you on what you're looking for (for instance, affordability, tax rates, traffic/commute options), a competent Realtor who knows the area would be perfectly safe, ethically, to make recommendations. Or if you wanted an informed opinion in which areas are most likely to appreciate in the next few years.
What we can't do is answer your question if you say you want to live in an area that is primarily one ethnic or racial group, or in an area that is devoid of a particular racial or ethnic group. And there are similar limitations regarding age, handicap, and a number of other factors. We also can't directly answer the question: "Which one has the better school system?" Because "better" is a relative term: You may consider better to be, for instance, the average SAT scores while someone else may consider "better" to be ones with great special education programs.
So: Define what, in your mind, consistitutes "better." Recognize that there are some areas (race, ethnicity, age of population, religion, and so on) that a Realtor can't address. Then discuss your likes and dislikes with a Realtor familiar with the areas you're interested in.
Hope that helps.
